ChemSpider RPC API v1.0

The ChemSpider SOAP API enables developers to work with ChemSpider's database of chemical structures, properties, and associated information. This is a legacy API which is being replaced by ChemSpider's new, RESTful API. ChemSpider is a free chemical structure database that provides search access to more than 67 million structures from hundreds of data sources.
